They are burned before the outbreak of spring in the following spring; Garden weeds eliminate early spring host; timely irrigation, increase the relative humidity in the field, create an ecological environment that is not conducive to the occurrence of leafhoppers; control the amount of nitrogen fertilizer application, increase phosphate fertilizer and potash fertilizer, and increase tree vigor. When pesticides are controlled, the fruit grower can spray a 3 to 5 degree lime sulfur mixture before germination. In addition, we must pay close attention to prevention before and after flowering. The period from the end of June to August is the fastest period of leafhopper breeding, and the generation overlap is serious. At this time, it is best to choose the konjac, broom, avermectin, and triazole which have good killing effect on each pod. Tin and other agents. Greenhouse Vertical Hydroponics
